#334 - Cardiovascular disease, the number one killer: development, biomarkers, apoB, cholesterol, brain health, and more | Tom Dayspring, M.D. 02/03/2025

#334 - Cardiovascular disease, the number one killer: development, biomarkers, apoB, cholesterol, brain health, and more | Tom Dayspring, M.D. Tom Dayspring is a world-renowned expert in clinical lipidology and a previous guest on The Drive. In this episode, Tom explores the foundations of atherosclerosis and why atherosclerotic cardiovascular disease (ASCVD) is the leading cause of death worldwide for both men and women. He examines how the disease develops from a pathological perspective and discusses key risk factors, including often-overlooked contributors such as insulin resistance and chronic kidney disease. He breaks down the complexities of cholesterol and lipoproteins—including LDL, VLDL, IDL, and HDL—with an in-depth discussion on the critical role of apolipoprotein B (apoB) in the development of atherosclerosis. Additionally, he covers the importance of testing various biomarkers, the impact of nutrition on lipid levels, and the vital role of cholesterol in brain health, including how cholesterol is synthesized and managed in the brain, how it differs from cholesterol regulation in the rest of the body, and how pharmacological interventions can influence brain cholesterol metabolism. We discuss: Defining atherosclerotic cardiovascular disease (ASCVD): development, risks, and physiological impact [2:45]; The pathogenesis of ASCVD: the silent development over decades, and the importance of early detection for prevention of adverse outcomes [10:45]; Risk factors versus risk markers for ASCVD, and how insulin resistance and chronic kidney disease contribute to atherosclerosis [17:30]; How hyperinsulinemia elevates cardiovascular risk [24:00]; How apoB-containing lipoproteins contribute to atherosclerosis, and why measuring apoB is a superior indicator of cardiovascular risk compared to LDL cholesterol [29:45]; The challenges of detecting early-stage atherosclerosis before calcification appears [46:15]; Lp(a): structure, genetic basis, and significant risks associated with elevated Lp(a) [55:30]; How aging and lifestyle factors contribute to rising apoB and LDL cholesterol levels, and the lifestyle changes that can lower it [59:45]; How elevated triglycerides, driven by insulin resistance, increase apoB particle concentration and promote atherosclerosis [1:08:00]; How LDL particle size, remnant lipoproteins, Lp(a), and non-HDL cholesterol contribute to cardiovascular risk beyond apoB levels [1:21:45]; The limitations of using HDL cholesterol as a marker for heart health [1:29:00]; The critical role of cholesterol in brain function and how the brain manages its cholesterol supply [1:36:30]; The impact of ApoE genotype on brain health and Alzheimer's disease risk [1:46:00]; How the brain manages cholesterol through specialized pathways, and biomarkers to track cholesterol health of the brain [1:50:30]; How statins might affect brain cholesterol synthesis and cognitive function, and alternative lipid-lowering strategies for high-risk individuals [1:57:30]; Exciting advancements in therapeutics, diagnostics, and biomarkers coming in the next few years [2:09:30]; Recent consensus statements on apoB and Lp(a) from the National Lipid Association (NLA) [2:12:30]; and More.

Improve your decision-making, frameworks for learning, backcasting, and more | Annie Duke (#60 rebroadcast) 09/02/2024

Improve your decision-making, frameworks for learning, backcasting, and more | Annie Duke (#60 rebroadcast) In this episode, former World Series of Poker champion and author Annie Duke explains how poker is a pertinent model system for decision-making in the real world, a system which blends imperfect information with some unknown percentage of both luck and skill. Annie breaks down the decision-making matrix, revealing how we often focus too narrowly on just one of the four quadrants, missing out on valuable learning opportunities in the remaining 75% of situations. She delves into how our tendency to evaluate only negative outcomes leads to a culture of risk aversion. This mindset, she argues, stifles the kind of bold decision-making necessary for progress and innovation across various fields, from poker and sports to business and medicine. Annie also introduces a robust framework for learning and the levels of thought required to excel in any domain. Finally, she discusses a strategy called “backcasting”, a concept that resonated deeply with Peter in terms of how he thinks about extending healthspan.
